Assasination class

ANOTHER TALKIE! I am just bored and i have many ideas because i watch assasination classroom again and i have many ideas. Now they are in the hotel while the most of the class got injected and is in the other hotel on this one island. This is where they fight against this one dude who smashed the glass(he is an assasin and he is rude and very violent) while the others are there but this time, you have to do it, i dont know if you want to talk or fight but both will be hard. You are also in the class of nagisa, karma, kayano and the entire other. The characters: Karasuma-sensei(he can not move well because of this gas), koro-sensei(he is in his form where he is in his ball form and cant move), Nagisa, kayano, karma, add the others if you want
